Does microperimetry have a role in monitoring visual function in patients with Behçet uveitis?

Abstract

Abstract Background To evaluate the change in time in visual acuity, central macular thickness (CMT), and microperimetry (MP) findings in Behçet uveitis (BU) patients who were in remission with maintenance therapy. Methods This single center, retrospective, observational cohort study included twenty-five eyes of 25 patients with BU who were in remission during maintenance therapy. Best corrected visual acuity (BCVA), CMT, macular integrity index, average threshold, and fixation stabilities (P1 and P2) evaluated at six-month intervals were recorded. The changes in time were statistically analyzed. Paired samples t-test was used for normally distributed data and Wilcoxon rank test was performed for non-normally distributed data. Results The mean BCVA and CMT showed no significant changes after six months. Although the mean macular integrity index decreased and the mean fixation stabilities increased after six months, these findings were not statistically significant. The mean average threshold was 16.8 dB at baseline and it increased significantly to 19.3 dB in the sixth month (p < 0.001). Conclusions The results of our study suggest that although visual acuity and CMT showed no change in patients with Behçet uveitis receiving maintenance therapy, MP could detect an improvement in macular function.
